gear up, deep sand bogs the hell out of your bike. if you normally run a 49tooth, run a 50. also if its 2 stroke, mix a tad rich,cuz you will be revving your bike out more in the sand. dont know your normal jetting, but you may have to tune that in a tad diff for the sand. last but not least, take it easy at first, riding on a paddle is TOTALLY different than the dirt your used to. its also not a bad idea to put tape over the side holes on your airbox (less chance of getting sand in the box), and make sure your chain is lubed up real good.
